Transcribe first, then set timing as the video plays.
control + t : If a timestamp field has focus, write timestamp into that field and move focus to next time field.
control + space bar : Play / pause video.
control + r : Rewind video one second.
Clicking the dynamic timestamp in the "video time" column pushes time into that subtitle row. This is helpful for adding the timestamp to a line of text during video playback. Timestamp is in total seconds. For example: two minutes and ten seconds is a timestamp of 130. You can also use the control + t key combo for this.
Set text timing about ½ second before dialog appears. This gives the brain time to react and read the text with the action. When setting timing with the "video time" link, this happens automatically.
100 character limit each text line.
During video playback, displayed text will fade out after six seconds. You don't need to add a blank line after text to clear subtitles.

Two lines cannot have the same timestamp.
